abstract
A feeding trial of 120 days was conducted on 16 Gir cows distributed equally in four groups to study the effect of feeding of hydroponics maize fodder on haemato-biochemical parameters and fed different levels of hydroponics maize fodder. The animals in group T₁ (control) were fed a 4.5 kg concentrate mixture (CP 20%) and wheat straw ad lib. In group T_2, 75% of CP was met through concentrate mixture (4.1kg) and rest through hydroponics maize fodder (5.6kg) along with wheat straw ad lib. Were provided. While in group T₃, 11 kg hydroponics maize fodder and 2.75 kg concentrate mixture were given along with ad lib. Supply of wheat straw. In the T₄ group, the animals were fed 16 kg of hydroponics maize fodder, 1.375 kg concentrate mixture and ad lib. Wheat straw. The haemato-biochemical parameters studied i.e. haemoglobin, packed cell volume, blood glucose, total serum protein, blood urea nitrogen and serum creatinine were well within the normal range and there were non-significant differences among the treatment groups. In respect of blood profile concerns, the blood profile in all the groups were similar for Hb, blood glucose, total serum protein and blood urea nitrogen showing non-significant differences among them. Based on the results, the study revealed that hydroponics maize fodder fed all groups shows non-significant effect on all blood constituents in Gir cattle indicated that the cows were having more or less similar physiological status.
